Left: dereddened CMD for the pointing containing the Palomar 5 stream as its primary feature; the template main sequence function and the turnoff point (green) are plotted for the maximum of the cross-correlation. The secondary main sequence at fainter magnitudes corresponds to the faint arm of the Sgr stream. Right: weighted-density diagram resulting from the cross-correlation. The maximum (white bin, black cross) marks the top left corner of the template-MS function at the position of the Palomar 5 stream’s main sequence, whereas the cyan overdensity at fainter magnitudes corresponds to the Sgr stream.
